摘　　要：用惠更斯原理对震后火灾的动态蔓延过程进行了模拟,并开发了基于GIS的城市地震次生火灾动态蔓延模拟系统,该系统可以模拟单个或者多个起火点的动态蔓延过程。研究结果可以定量地估计地震次生火灾对城市的危害,从而在最短时间内给救灾应急提供决策依据。The dynamic simulation of fire following earthquake was researched by employing of Huygens＂ Principle. A dynamic simulation system of post-earthquake fire based on GIS was developed. The system can be used to simulate spread process of one fire spot and multi fire spots. The system can estimate the damage of fire fol- lowing earthquake quantificationally, and provided foundation for emergency in short time.
